Keith McMillen Instruments 12 Step



12 Step opens up another dimension in performance by giving your feet unprecedented control over expressive gestures. Play and control your soft-synths, keyboards or sound modules via USB or MIDI. Latch notes or chords, toggle them on/off or play legato. Foot Pressure and Key Tilt supports Channel Pressure and Polyphonic Aftertouch for highly expressive performance gestures. 12 Step is easy to see on stage thanks to the backlit keys and display. Use it with your iPad and iOS devices - just plug and play! Optional MIDI Expander is required to connect to MIDI hardware.
